Embodiment
Seeing also Fig. 3, is the perspective exploded view of the module backlight that disclosed of a kind of better embodiment of the utility model.This module 20 backlight comprises a light guide plate 21, one light tube group 23, an one glue frame 25 and a backboard 27, this light guide plate 21 comprises an incidence surface 211 and one and the exiting surface 213 of these incidence surface 211 adjacent settings, the incidence surface 211 of these light tube group 23 relative these light guide plate 21 is provided with, and this backboard 27 cooperates this glue frame 25 to accommodate this light guide plate 21 and this light tube group 23.
Seeing also Fig. 4, is the solid assembling synoptic diagram of the light tube group 23 of module backlight 20 shown in Figure 3.This light tube group 23 comprises fluorescent tube 231, lamp tube cover 232, one first cramping body 233, one second cramping body 235 and four leads 237 around this two fluorescent tube 231 that two parallel interval are placed.In this module 20 backlight, this fluorescent tube 231 is a cathode fluorescent tube.This first cramping body 233, this second cramping body 235 are enclosed within the two ends of this two fluorescent tube 231 respectively, with this two fluorescent tube 231 of clamping.These four leads 237 correspondingly link to each other with the end of this two fluorescent tube 231 respectively.
See also Fig. 5 and Fig. 6 again, Fig. 5 is the partial enlarged drawing of the part of V shown in Fig. 4 light tube group 23, and Fig. 6 is the partial enlarged drawing of another angle of the part of V shown in Fig. 4 light tube group 23.First cramping body 233 of this light tube group 23 comprises a fixing end 2331 and a leading-out terminal 2333 vertical with this fixing end 2331.This fixing end 2331 and this leading-out terminal 2333 are made by elastomeric material, and this fixing end 2331 is one-body molded with this leading-out terminal 2333, promptly by injection forming method disposal molding this fixing end 2331 and this leading-out terminal 2333.
Wherein two leads of these four leads 237 successively through this fixing end 2331, with the perpendicular leading-out terminal 2333 of this fixing end 2331 after directly draw, these two leads have been bent 90 degree; In addition two leads are then after this second cramping body 235 is drawn, extend to along the back side of this lamp tube cover 232 these first cramping body, 233 places and with two lead parallel arranged of drawing from this first cramping body 233, two leads are also by one 90 degree of folding in addition.Therefore, when this lead 237 is subjected to pulling force, this pulling force can not act directly on the solder joint position that this lead 237 is connected with this fluorescent tube 231, avoid the straight line of 231 of this lead 237 and this fluorescent tubes stressed, the effective suffered pulling force of this lead of buffering 237, make the solder joint between this lead 237 and this fluorescent tube 231 ends be difficult for being drawn pine, avoid this lead 237 to be broken simultaneously.
The fixing end 2331 of this first cramping body 233 and leading-out terminal 2333 also can be arranged to mutually independently rubber element, and promptly this fixing end 2331 separates with this leading-out terminal 2333.The method of the end of this leading-out terminal 2333 by being enclosed within this fixing end 2331 is formed the first complete cramping body 233.Produce this first cramping body 233 by this method and can be convenient to the production of actual product and the simplification of package program.
See also Fig. 7 and Fig. 8, Fig. 7 is another angle schematic perspective view of the glue frame 25 of module backlight 20 shown in Figure 3, and Fig. 8 is the partial enlarged drawing of VIII part shown in Figure 7.This glue frame 25 comprises the projection 255 that a first side wall 251, one second sidewall 252, one the 3rd sidewall 253, one the 4th sidewall 254 and extend internally from this second sidewall 252.This first side wall 251, this second sidewall 252, the 3rd sidewall 253 and the 4th sidewall 254 vertically link to each other successively.This projection 255 is a curved surface (not indicating) near a side of this first side wall 251, wherein this curved surface comprises one first arc sections 2551, a junction 2552 and one second arc sections 2553, and this first arc sections 2551 links to each other with this second arc sections 2553 by this connecting portion 2552.This first arc sections 2551 is an inner concave arc surface, and this connecting portion 2552 is a plane, and this second arc sections 2553 is an outer convex globoidal, this second arc sections 2553 than this first arc sections 2551 away from this first side wall 251.
Seeing also Fig. 9, is the partial enlarged drawing of this light tube group 23 and 25 combinations of this glue frame.The position that this light tube group 23 is set is to the first side wall 251 that should glue frame 25.Wherein, first cramping body 233 of this light tube group 23 is arranged on the first side wall 251 of this glue frame 25 and second sidewall, the 252 crossing formed corners of this glue frame 25.The fixing end 2331 of this first cramping body 233 attaches the first side wall 251 of this glue frame 25, second sidewall 252 of leading-out terminal 2333 these glue frames 25 of attaching of this first cramping body 233 and relative with the projection 255 of this second sidewall 252.
When this glue frame 25 makes up with this light tube group 23, first arc sections 2551 of this projection 255 closely compresses this lead 237, therefore when this lead 237 is subjected to a lateral pull, this lateral pull can directly not involve the solder joint between this lead 237 and this fluorescent tube 231 ends, guarantees that this lead 237 is good with contacting of these fluorescent tube 231 ends.
See also Figure 10 and Figure 11, Figure 10 is the assembly drawing of module backlight 20 shown in Figure 3, and Figure 11 is the partial enlarged drawing of X part shown in Figure 10.The backboard 27 of this module 20 backlight is one to have the iron plate of a peristome 271.This peristome 271 comprises one first limit 2711, one second limit 2713 and one the 3rd limit 2715, and this first limit 2711 is oppositely arranged with the 3rd limit 2715, and this first limit 2711, this second limit 2713 and the 3rd limit 2715 vertically link to each other successively.Wherein, this second limit 2713 bends inwards and is circular shape.
In this module 20 backlight, second sidewall 253 that 271 pairs of the peristomes of this backboard 27 should glue frame 25.The lead 237 of drawing from the leading-out terminal 2333 of this light tube group 23 is retracted to this peristome 271, and extend at the back side along this backboard 27 after bending, with external power supply.Wherein, the 3rd limit 2715 parts of this leading-out terminal 2333 outstanding these peristomes 271, so there is certain interval on 2715 on the 3rd limit of this lead 237 and this peristome 271, avoids this lead 237 by the edge institute scratch on the 3rd limit 2715 of this peristome 271; And second limit 2713 of this peristome 271 is circular arc, even therefore the edge on this second limit 2713 can rub with this lead 237, and can this lead 237 of scratch yet.
Compared to prior art, because of the light tube group 23 of the utility model module 20 backlight is provided with one first cramping body 233, and this first cramping body 233 comprises a fixing end 2331 and a leading-out terminal 2333 vertical with this fixing end 2331.Therefore by this leading-out terminal 2333, this lead 237 is drawn after being certain bending state, avoids the straight line of 231 of this lead 237 and this fluorescent tubes stressed, can effectively cushion the suffered pulling force of this lead 237.
In addition because the edge on second limit 2713 of the peristome 271 of this backboard 27 is set to circular shape, when avoiding this lead 237 to rub mutually with the edge on this second limit 2713 by scratch.
Certainly, in this module 20 backlight, the fluorescent tube 231 of this light tube group 23 and this light tube group 23 is not limited to above-mentioned number.According to the actual needs, relatively another the side placement relative with this incidence surface 213 of this light guide plate 21 of another light tube group can be set; The fluorescent tube 231 of this light tube group 23 also can be set to single or more than two so that offer this module 20 appropriate brightness backlight, the quantity of this multiple conducting wires 237 also correspondingly reduces or increases; Simultaneously, the number of the projection 255 of this glue frame 25 also can be arranged on close the 3rd sidewall 253 1 sides of this second sidewall 252, and is corresponding with another newly-increased light tube group.
